The surface roughness is the measure of the total spaced irregularities on the surface. Whenever machinists talk about "surface finish," they often refer to surface roughness. Waviness refers to the warped surface whose spacing is greater than that of surface roughness length. And lay refers to the direction the predominant surface …
Since surface roughness of Rmax/Rz=1.6s can be achieved, hard turning is often considered a replacement for grinding operations or as a pre-grinding process. Hard turning is most often …
Roughness is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form, if the deviations are large, the surface is rough, if they are small, the surface is smooth. Roughness generally caused by a manufacturing process or material condition.
